NASA Aero View of Small Business Role

NASA Aero leverages both in-house and external expertise to address researchand development needs

External collaborations include other government agencies, academia, andindustry (large, medium, and small businesses)

External research is competition-based and includes Task Order Contracts, NASAResearch Announcements (NRA), and SBIR/STTR

SBIR/STTR awards integral part of overall competitive acquisition strategy Tap into vast intellectual capital and innovative ideas in small business community

Serve as catalyst for small business growth and expansion

Topic A1 and T15 Overview A1 one of three Aero-sponsored topics and addresses 5 of 6 strategic thrusts Broken down into subtopics that reflect enduring themes relevant to Aero Strategy Each Subtopic further broken down into focus areas

Focus areas updated annually based on current outlook

Subtopic breakdown meant to (1) identify specific needs, (2) ensure relevant proposals,(3) save you time and effort

10 SBIR subtopics for 2017 Phase 1 (9 last year) 7 with a new focus area within the subtopic

1 with a slightly refined focus area

1 cross-cutting area that is essentially unchanged

1 new in Hypersonic Technology
